Pancreaticoduodenectomy for borderline resectable pancreatic head cancer with a modified artery-first approach technique

BACKGROUND: The treatment of borderline resectable pancreatic head cancer (BRPHC) is still controversial and challenging. The artery-first approaches are described to be the important options for the early determination. Whether these approaches can achieve an increase RO rate, better bleeding control and increasing long-term survival for BRPHC are still controversial. We compared a previously reported technique, a modified artery-first approach (MAFA), with conventional techniques for the surgical treatment of BRPHC. METHODS: A total of 117 patients with BRPHC undergone pancreaticoduodenectomy (PD) from January 2013 to June 2015 were included. They were divided into an MAFA group (n=78) and a conventional-technique group (n=39). Background characteristics, operative data and complications were compared between the two groups. RESULTS: Mean operation time was significantly shorter in the MAFA group than that in the conventional-technique group (313 vs 384 min; P=0.014); mean volume of intraoperative blood loss was significantly lower in the MAFA group than that in the conventional-technique group (534 vs 756 mL; P=0.043); and mean rate of venous resection was significantly higher in the conventional-technique group than that in the MAFA group (61.5% vs 35.9%; P=0.014). Pathologic data, early mortality and morbidity were not different significantly between the two groups. CONCLUSIONS: MAFA is safe, simple, less time-consuming, less intraoperative blood loss and less venous resection, and therefore, may become a standard surgical approach to PD for BRPHC with the superior mesenteric vein-portal vein involvement but without superior mesenteric artery invasion.
